Calibrachoa plant named ‘Suncal 1871’

ABSTRACT

A new and distinct cultivar of  Calibrachoa  plant named ‘Suncal 1871’, characterized by its compact and mounding plant habit; vigorous growth habit; freely branching habit; early and freely flowering habit; long flowering period; white-colored flowers with bright yellow-colored throats; and good garden performance.

Botanical designation: Calibrachoa sp.

Cultivar denomination: ‘SUNCAL 1871’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Calibrachoa plant, botanically known as Calibrachoa sp. and hereinafter referred to by the name ‘Suncal 1871’.

The new Calibrachoa plant is a product of a planned breeding program conducted by the Inventor in Higashiomi, Shiga, Japan. The objective of the breeding program is to develop new compact, mounding and freely branching Calibrachoa plants with numerous large and attractive flowers with unique coloration.

The new Calibrachoa plant originated from a cross-pollination conducted by the Inventor in Higashiomi, Shiga, Japan in September, 2012 of a proprietary selection of Calibrachoa sp. identified as code number C24F1-81-1, not patented, as the female, or seed, parent with a proprietary selection of Calibrachoa sp. identified as code number C24-162-1, not patented, as the male, or pollen, parent. The new Calibrachoa plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Higashiomi, Shiga, Japan in October, 2013.

Asexual reproduction of the new Calibrachoa plant by terminal vegetative cuttings in a controlled greenhouse environment in Higashiomi, Shiga, Japan since November, 2013 has shown that the unique features of this new Calibrachoa plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Calibrachoa have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Suncal 1871’. These characteristics in combination distinguish ‘Suncal 1871’ as a new and distinct Calibrachoa plant:

-   -   1. Compact and mounding plant habit.     -   2. Vigorous growth habit.     -   3. Freely branching habit.     -   4. Early and freely flowering habit.     -   5. Long flowering period.     -   6. White-colored flowers with bright yellow-colored throats and         venation.     -   7. Good garden performance.

Plants of the new Calibrachoa can be compared to plants of the female parent selection. Plants of the new Calibrachoa differ primarily from plants of the female parent selection in flower color as plants of the female parent selection have red and yellow-colored flowers.

Plants of the new Calibrachoa can be compared to plants of the male parent selection. Plants of the new Calibrachoa differ primarily from plants of the male parent selection in flower color as plants of the male parent selection have pink and yellow-colored flowers. In addition, flowers of plants of the new Calibrachoa are smaller than flowers of plants of the male parent selection.

Plants of the new Calibrachoa can also be compared to plants of Calibrachoa sp. ‘Sunbel 789’, disclosed in U.S. Plant Pat. No. 26,444. In side-by-side comparison, plants of the new Calibrachoa and ‘Sunbel 789’ differ primarily in the following characteristics:

-   -   1. Plants of the new Calibrachoa are larger than plants of         ‘Sunbel 789’.     -   2. Plants of the new Calibrachoa have thicker lateral branches         than plants of ‘Sunbel 789’.     -   3. Plants of the new Calibrachoa and ‘Sunbel 789’ differ in leaf         shape as plants of ‘Sunbel 789’ have spatulate-shaped leaves.     -   4. Plants of the new Calibrachoa have smaller flowers than         plants of ‘Sunbel 789’.     -   5. Plants of the new Calibrachoa and ‘Sunbel 789’ differ         slightly in flower color.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the summer in 15-cm containers in an outdoor nursery in Higashiomi, Shiga, Japan and under cultural practices typical of commercial Calibrachoa production.
